Hydro Wins Thames Wastewater Contracts

CLEVEDON, U.K. - Thames Water has awarded two significant wastewater treatment equipment supply contracts to Hydro International as part of its £3 billion five-year investment programme to improve water and waste water facilities between 2005 and 2010.  Hydro will supply equipment to improve primary sludge settlement tank operation and removing fine suspended solids in contracts worth more than £3 million. Hydro Managing Director for Europe, Chris Williams comments: “These contracts demonstrate the increasing investment by the water industry as part of the AMP4 round, and are recognition of the performance of our innovative water treatment technology.” As part of the ongoing upgrade at Beckton STW, Barking, Hydro is supplying Zickert longitudinal tank bottom scrapers, scum scrapers and other associated equipment to improve primary sludge settlement performance in two of the sixteen existing primary settlement tanks.

Thames Water procurement engineer Mike Shunn commented: “As per EU guidelines, the Zickert system scrapers were evaluated for economic advantages, and offered the best whole life cost of the alternatives. In addition, they have a low profile should we need to enclose the tanks at some stage.”  Installation is expected to be complete for January 2008. At Hogsmill STW in Kingston, as part of an Thames Water AMP4 Alliance contract with Costain Ltd, Hydro DynaDisc™ Filter technology is being installed to improve fine suspended solids removal from treated effluent prior to discharge.  DynaDisc™ Filter units are being supplied with a total maximum flow rate of 4698 l/sec.

Neil Dugmore, Costain Project Manager at Hogsmill STW commented: "Thames Water wished to further enhance treatment effectiveness and water quality at the works and the Hydro DynaDisc™ was a cost-effective, high performance solution, which could be supplied on a very short lead time." Installation is scheduled for September 2007.
